OID_WW_CDPD_CS_INFO
The OID_WW_CDPD_CS_INFO OID requests the miniport driver to return current information about circuit-switched CDPD connections.
This request uses a WW_CDPD_CS_INFO structure, defined as follows:
typedef struct _WW_CDPD_CS_INFO {
INT ConnectRate;
NDIS_VAR_DATA_DESC DialCode;
UINT SID;
INT ABSideSelection;
INT AMPSChannel;
} WW_CDPD_CS_INFO;
The members of this structure contain the following information:
ConnectRate
Specifies circuit-switched bit rate. A value of 0 specifies no active connection. A value of -1 specifies an unknown rate. All other values specify the current rate represented as bits per second.DialCode
Describes a buffer that contains the last dial code used to establish a CS-CDPD connection.SID
Specifies the current AMPS system identifier.ABSideSelection
Specifies the side channel that is currently selected. The following lists valid values.Value Meaning 0
No AMPS service
1
AMPS "A" side channel selected
2
AMPS "B" side channel selected
-1
Unknown
AMPSChannel
Specifies the AMPS-channel number that is currently in use. A value of 0 specifies no AMPS service. A value of 1 through 1023 specifies the current AMPS channel in use. A value of -1 specifies the channel number is unknown. All other values are reserved.
The miniport driver should return a value of NDIS_STATUS_NOT_SUPPORTED if the current mode of operation is via packet-switched CDPD. For more information, see OID_WW_CDPD_CS_SERVICE_STATUS.
Sets and indications are irrelevant for this OID.
